Scordatura
Encyclopedia : S : SC : SCO : Scordatura
A scordatura (literally Italian for "mistuning") is an alternate tuning used for the open strings of a string instrument. It is an extended technique used to allow the playing of otherwise impossible melodies, harmonies, figures, chords, or other note combinations.
Scordatura in classical music
- Mozart, viola in Sinfonia Concertante for Violin, Viola and Orchestra. Changing the pitch of the open strings to a semitone higher was in this case probably primarily intended to make the viola sound louder, and so better discernable in the symphonic orchestra: indeed, increasing the tension in a string, not only sharpens the pitch, but also makes it sound louder, the loudest sound being obtained just before breaking.
- Mahler, scordatura violin soloist in the 2nd movement of his 4th Symphony. In this case the composer probably intended primarily the specific (tone)"color" of the sound produced by a scordatura violin, which is less suave than the sound of a standard tuning.
- Saint-Saëns, solo violin in Danse Macabre, where the E-string is tuned to Eb.
- Igor Stravinsky's The Firebird is a rare, perhaps unique, piece which calls for the entire violin section to retune a string, in order to play some natural harmonics.
- Bach's fifth cello suite requires the soloist to tune down the highest string from an A to a G.
- the cello in George Crumb's chamber work Vox Balaenae (scored for electric flute, electric cello, and electric piano). The traditional C-G-D-A tuning is changed to B-F#-D#-A, which serves to emphasize the key of B major that emerges in the final movement.
- Zoltán Kodály's solo cello sonata in B minor requires the cellist to tune down the two lower strings from G and C to F# and B, to emphasize the key with reoccurring B-minor chords.
- Ligeti's Violin Concerto
- Schnittke's Monologue for viola and strings
- Schumann's Piano Quartet in E-flat, Op.47, requires the cellist to retune the C string down to B-flat for the finale.
- In some double bass solo music, a specific solo tuning (F#-B-E-A) that requires a different set of strings is used. This is to allow the bass to be heard better over the piano or orchestra. With better instrumental technology and string manufacturing, orchestrally tuned (E-A-D-G) bass editions are becoming more common.
Scordatura in folk music
Scordatura is commonly used on the fiddle in folk music of Appalachia and the southern United States. The fiddle may be re-tuned in any number of ways in these musical idioms, but there are two common re-tunings. While the standard tuning for open strings of the violin is GDAE—with the G being the tuning of the lowest-pitched string and the E being the tuning for the highest-pitched string—fiddlers playing tunes in the key of D major sometimes employ a tuning of ADAE. In this tuning the open G string is raised to the A directly above it. Even more frequently used is a scordatura tuning of AEAE for music played in the key of A major. Among fiddlers this is referred to as "cross-tuning." In both of these scordatura tunings, scordatura facilitates a drone on an open string next to the string on which the melody is being played. Relatively well-known American folk tunes that are often played in cross-tuning include "Breaking Up Christmas," "Cluck Old Hen," "Hangman's Reel," "Horse and Buggy," and "Ways of the World."
GDAE is known in some North American Old-Timey fiddling circles as "that Eye-Talian tuning," the implication being that it is only one of many possibilities. Other tunings include:
- FCGD = Cajun Tuning (one whole step down from GDAE)
- GDGB = Open G Tuning
- GDGD = Sawmill Tuning
- GDAD = "Gee-Dad"
- DDAD = Dead Man's Tuning, or Open D Tuning, or Bonaparte's Retreat Tuning, or "Dee-Dad"
- ADAE = Old-Timey D Tuning
- AEAE = High Bass, High Counter (or High Bass, High Tenor) similar to Sawmill Tuning
- AEAC# = Black Mountain Rag Tuning, or Open A Tuning
- AEAD for Old Sledge, Silver Lake
- EDAE for Glory in the Meeting House
- EEAE for Get up in the Cool
